MOP

Filed June 5, 1929 Patented Sept. 27, 1932 UNITED STATES PATENT oFFIcE i 4 ARTHUR C. KOOIZ, OF MILWAUKEE, WISCONSIN, ASSIGNOR TO THE GEM HAMMOCKL FLY NET COMPANY, F MIIJWAKEEI, WISCONSIN, A. CORPORATION OF WISCONSIN' MOP Application led .Tune 3, l19529. Serial No. $368,643.

The-invention relates to mops andmore particularly to the means for adjustably,

pivotally connecting the mop head withv the handle. Y j 5 Portions of the mop head and the connector are usually made of ymetal and in order to prevent these metal parts from coming in Contact with'and marring the surfaces being cleaned, oneof the objects of this invention is to provideffa pad, preferably ofsheepskin with the eece thereon, which surrounds the end of the connector where it Yjoins the mop frame and is firmly secured thereto, at its ends, preferably by the means for clamping En the connector to the mop head. In this connection, it is also an object of the invention toV provide the connector withV depressions adjacent the clamping bolt so that the head of the bolt and the clamping nutkwill bedepressed below the main body of the connector and be protected by the pad and at the same time these depressions act as strengthening corrugations for they jaw portions of the connector. Y A further object of the vinvention is to provide a handle connector of one-piece construction in which the rear portion is clamped to the handle by a .clamping bolt separate from the bolt that adjustably clamps the jaws to the mop head so that the mop head may be readily and firmly secured to any suitable round handle and special lhandles need not be furnished. Furthermore, a firm, clamping engagement with the handle is assured and the pivotal adjustment of the head relative to the jaws may be effected without danger of loosening the connector from the handle. Y The invention further consists in the several features hereinafter set forth and more particularly defined byV claims at the conclusion hereof. n g

In the drawing Fig. 1 is a plan view of a mop embodying the'invention, parts of the connector being shown in section and part of the handle being broken away; Y

The invention has been shown applied to the so-called wire-bound mops and Vwhile this isthe preferredconstruction, the protector and connector hereinafter described are not to be limited to use on this form of mop head, as the invention is applicable to other types of mop heads having pivoted handles. e ,j i

As herein shown, .the mop element consists of strands 5 of mop material clamped to a wire vframe in known manner, sald frame comprising a pair, of wires 6 between which j the mop strands areinitially placedA soas tovr extend outwardly therefrom, afterV which. the wires, held at one end and turnedrat the other end, are twisted together "along their i length and in being twisted firmly clamp the mop strands between them. Y Y E In order to firmly hold the ends of the wire of the type shown and described` in my co-r pending application Serial No. 121,882, filed- July 12,1926. This coupling member v7 consists of a piece of steel ory other relatively hard, ductile metal which is turned to provide a conica-lly curved, ycentral portion S andY end bosses 9,' and is provided 'with a central bore10 into whichthe ends of the wire frameMa-re inserted and in. which they frame together,vI prefer to use the coupling i v are firmly secured, as in theaforementione'd application, by swagging or upsetting por-YV tions 11 of the end bosses 9 soy that the bore 10 is 'distorted andh its side walls brought into firm, permanently crimped engagementA with the wires. j

The handle 12 may have a plain or slightlyl reduced end portion 13 jthat lits into the cylindrical,;split, rear end Aportion 14 of theV sheet metal connector 15 whichisY formed from a single blank 'of sheet metal pressed ,i at this end into tubular form, with'laterally extending 'spaced ears v.15"f`at one-side pro; vided with openings to receive a clamping bolt 16 provided with a nut 17 Vfor drawing the separated ends of said cylindrical portion together and into firm, clampingengagement .with the handle.

From this rear end portion 14 'the sheet metal blank is 'shaped to provide a vpair of Elu' les Y generally semi-cylindrical, resilient clamping jaws 18, having conically curved end portions 19 that are pressed out to lit and tightly engage the conically curved portion 8 of the coupling member 7, and are held in firm engagement therewith by a clamping bolt 2O that extends through openings 2l and 22 in said jaws and preferably has a squared shank portion 28 fitting in the opening 21 and a wing-nut 24 mounted on its threaded end, though an ordinary flat, square or hen'ag# onal nut may be used, said nut being on the top portion of the connector.V In order to reinforce the jaws and toV prevent kthe eti-- posed ends of the bolt fromsticling out, particularly the head, the lower jaw is pressed to provide a head-receiving ,depression 25 and the upper jaw is formed to provide a flattened` depression 26.y Where these depressedv portions merge with the side portions of the jawsstrengthening ribs 27 are formed. Furthermore, it `will be noted that the jaws are not formed asiiat, sheet metal projections, but are of curved, channelled construction so that theyk are very strong and considerable pressure can be imposed upon them by the clamping bolt 2O without danger of breakage or fatigue.

n. In order to protect the surfaces with which the mop may come in contact from the metal parts of the connector, a pad 28'of sheepskin with the fleece 29 thereon is adapted to eX- tend aroundv the top, front and bottom of the jaws and is secured in place by passing the bolt 2O through openings in said pad adjacent its ends, the lower end being clamped between the. washer 30 and the lower jaw, while the upper end is clamped between a washer 3l and thevupper jaw, the head and nut of the bolt being thus embedded in and protected by the surrounding ieecy material of the pad, the depressions 25` and26 also assisting in bringing the parts of the bolt 2O to a position for eective protection by the pad. Other forms of cushioning material may be used but the material sheepskin as above designated is preferred asit may be readily washed. y

y I desire it to be understood that this invention is not to be limited to any particular form or arrangement of parts except insofar .as such limitations are included in the claims.

What I claim as my invention is:

1*. A handle connector for mops comprising a single piece of sheet meta-l having a tubular portion at one end with separable end parts and a pair of resilient jaw portions extending from said tubular portion and separated in a plane coinciding with that of the separable end parts of said tubular portion, said jaw portions being of generally cylindrical shape having their endportions curved to receive a mop pivot and provided with alined openings adjacent their ends and depressed portions surrounding said openings,

an adjustable clamping bolt passing through said alined openings, and means for drawing the separable ends of said tubular portion into clamping engagement with a mop handle.

2. A handle connector for mops comprising a single piece of sheet metal having a tubular portion at one end with separable end parts and a pair of resilient jaw portions extending from said tubular portion and separated in a plane coinciding with that of the separable end parts of said tubular portion, said jaw portions being of generally cylindrical shape having their end portions curved to receive the mop pivot and provided with alined openings adjacent their ends and depressed portions surrounding said openings,

Va compressible protector pad extending around saidA jaw portions andV having alined openingsregistering `with the openings in the. jaw portions, an I adjustable clamping bolt passing through said Y jaws and pad", andv means 'for drawing the separable ends ofv said tubular portion into clampingengagement with a mop handle.

In testimony whereof, I afHX my signature.
